Low-Power Quad-Channel Digital Isolators
Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering sub-
stantial data rate, propagation delay, power, size, reliability, and external BOM advantag-
es over legacy isolation technologies. The operating parameters of these products re-
main stable across wide temperature ranges and throughout device service life for ease
of design and highly uniform performance. All device versions have Schmitt trigger inputs
for high noise immunity and only require VDD bypass capacitors.
Data rates up to 150 Mbps are supported, and all devices achieve propagation delays of
less than 10 ns. Enable inputs provide a single point control for enabling and disabling
output drive. Ordering options include a choice of isolation ratings (1.0, 2.5, 3.75 and 5
kV) and a selectable fail-safe operating mode to control the default output state during
power loss. All products >1 kV are safety certified by UL, CSA, VDE, and CQC, and
products in wide-body packages support reinforced insulation withstanding up to 5
kVRMS.
